Patenteanarch 27, 1906.

To all whom, it may concern: y l y Be it known that I, WILLIAM J. MORRISON,

` of Nashville, county of Davidson, State' of Tennessee, have invented an Improvement in Candy-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to certain improvements in thatclass of candy-machines whichv are adapted to convert ordinary granulated sugar into finely-attenuated threads, and

more particularly it relates lto certain improvements inv the device shown in the United States Patent to myself and John C.

Wharton, No. 717,756, of January 6, 1903.

The device of said prior patent is defective in various particulars, several-of the more important of which are as follows: In said prior device a satisfactory meansv was not rovided to prevent the dischar e of grains o unmelt'- i ed sugar with the me ted sugar which it is alone desired to dischar e. With said device, moreover, it was il'licult to prevent overheating of the sugar, and it is a fact that in order to secure desirableresults, suchv as v uniformity and fineness of 4the product, the

sugar must be thrown from the rotatin contalner -or vessel at a temperature 'whic but slightly exceeds the melting-point of sugar and that if this temperature is exceeded the product will not be delivered in threads of the desired uniform finenes's and the syrup is liable to' turn to caramel and clogor close the discharge-openin from the vessel. In said prior device the e ectric heater is more or less exposed to the open air, causingl the waste of heat to a very material extent'. From a long series of experiments I have reached the conclusion that a form of heater 'which consists kof a series of closely-arranged coils, folds, or

plaits is better adapted for this purpose than any other form 'o which I am, aware, and

with such a form of heater as theA number ofheating-sections in a given space is .liable to vary somewhat from those in an adjacentv spacev it followsthat the sugar or syrup may be heated to a higher temperature atvsome pointsL than at others, thereby preventing uniform results from being secured' and frequently causing more or less of the Sugar to turn to caramel. yWith said prior device, moreover, much `difliculty has arisenffrom My invention has for'its object to provide a device of the character above described with means which shall effectively prevent the escape of the grains of sugar before they are melted and which shall thorou hly strain4 the discharged syrup and deliver t e same in uniform threads or ribbons. ,l

A further object of my invention is to preyent contact of the outer air vWith the'electric heater, so as to reduce the amount of heat lost by'radiation and to provide a suitable insulatin -su port therefor.

A lgurtlier obj ect of my invention is to prevent any -portion Vof the syrup from being raised to too high a temperature and to provide means whereby the syrup may be dis- A rt er object of my invention is to provide means for assisting the centrifugal ac- 'tionofv lthe vessel in forcing the Syrup therefrom as fast as it is formed and in conveyingJ the finethreads tothe sides of the-collectingreceptacle to prevent them from being wound char ed ractically as rapidlyas it is formed.

about the vessel after they have been Udischarged.

I accomplish these` objects by the meansf shown in the accompanying drawings,- in

which- Figure 1 re resents a side elevation of a rotatable vesse or casing provided with my invention. Fig. 2 is a plan view taken on the line 2 2 of Fig. 1. ,Flgn 3 is a tolp plan view 'of the c'asing. Fig. 4 is a detai front view l partly broken away. Fig. -5 is a central section onthe line 5 5 of Fig. 2. Fi 6 is an en- 'larged-section on the linev 6.6 of- 'g. 2; Fig. 7 is a detailed view of a section of the resist-- TOD' ance-band. lFi 8 is an elevation, partly in section, ofthe w ole apparatus.

z The hollow caslng or vessela is mounted in a-collecting-receptacle a0 upon a vertlcal shaft a?, which is preferably secured to an armature-shaft of an electric motor, and said shaft a,2 is provided with contact-rings suitably insulated from each other, the electric current being conducted to and from said rings by brushes c. The vessel a comprises a base-plate d, which is secured to said shaft a', and a cap-plate e, which is connected thereto by clamping-bolts h, said plate e being provided with a central aperture, into which an inverted funnel f leads, as is in said prior device. ri`wo rings m and n are respectively arranged on the under side of plate e and upper side of plate d, said rings being respectively provided with annular grooves m n', the outer sides of which are formed by oppositelyextending circumferential iianges m2 n2. F itted in and seated against the bottoms of said grooves m n are a series of cylindrical rods g, preferably of tubular glass and of lequal length. Said rods are arranged'closely toether side by side, and the rin s m n are iirmly clamped against the ends or said tubes,

by bolts h', so that there is no space or opening therebetween. Said rods or tubes g are arranged closely side by side and may be bound together with wire for convenience after the manner illustrated in Fig. 6. While said rods g are'so arranged that thespaces between their sides are very narrow and will prevent the passage of solid matter even smaller than the finest grains of granulated sugar therebetween, yet said spaces are suliciently wide to permit liquid to pass therethrough, so that said tubes'unite to form a strainer.

Within the series of rods g is arranged a suitable highly-resistive electrical conductor band.

1', the form which I prefer to employ being made by helically winding a fiat reslstancewire, with the edges of the coils nearly touching and then pressing the same into a at The band thus formed maybe deined as composed of two contiguously-arranged'series of straight flat sections, the respective sections of each series having their edges closely adjacent', but out of Contact, the ends of each section of one series being respectively connected to the ends of a section of the other series and the sections -of each series respectively extending in parallelism transversely of the band at a corresponding but opposite angle of Obliquity.

An insulating-tube fi, ofv lass or other suitable material, 1s connecte to the inner side of the wall of the strainer, and the ends of the band 1 terminate at oppositesides thereof. The ends of the wire of which said band is composed are connected to binding-posts which are in turn connected to the ringsl b, said connecting wires preferably passing throu h and being located below an msulating fase bottom 7c, as shown in Fi s. 4 and 5. The side of-said band r referably ies against the inner side of the wall formed by the series "enabled to sierra of rods g, and the inner sides of the rings m n adjacent the edges of said band are either covered with an insulating enamel or iat rings y, of mica or other suitable insulating material, are provided thereon.

The upper ring m is provided with an annular air-chamber m3 at the inner side of its groove m. A series of ports p are provided in upper plate e, and inclined blades g are connected to said plate at corresponding sides of said ports. The side ofsaid chamber m3, which bears against the strainer-rodsg, is provided with perforations or slots s, as shown in Figs. 3 and 4. .A flat ring or damper t is arranged on the up er plate and adapted to vary the size or the passage through ports p.

The edge portions of the upper and lower plates al and e, which project beyond the outer side of the strainer-wall g, with a series of obliquely-disposed blades i: fv, arranged adjacent corresponding notches 'w w" in said edge portions.

The operation of the above-described device is as follows: The vessel is rotated at a high rate of speed and the granulated sugar is poured into the hopper and is carried-by centrifugal force against coil r. The sugar is'heated and passes between the coils of wire and against the inner sides of the strainer of glass tubes or rods g.

are each providedt e heating band or As the sugar reaches the melting-point the whirling motion will spread the syrup thus formed over the inner surface of thestrainer in a iilm and will force the syrup through the spaces between the rods g, thereby causing t e sugar to be drawn into fine threads or ribbons as it is thrown ofi. The rods g be-` cdme heated to the temperature ofthe sugar as it is discharged, and as the syrup flows circularly on the inner face of the strainer a tendency to overheat the sugar at a articular section of the heater by reason of t ere being a greater number of coils therein than in another section is in a great measure counteracted. This is a hi hly-important feature of my invention, for am thereby ipractically revent the sugar from ein overheated an to discharge the sugar w le at the melting-point, approximately, and as soon Vas possible after it of closel'v-arranged glass-cylinders not only effective y prevents the escape of all unmelted grains of sugar and thoroughly strains the melted sugar, but it also acts as a perfect insulating transverse support for the heater ge. e

and prevents in a lar gre'e the radiation of heat from the heater while the apparatus is being rotated. The vessel is rotated in such a direction with relation to the position of the blades q (indicated by the arrow in Fig. 3) that they will cause air to beforced into the .air-chamber 'ma and ont'through the ports s therein againstk the inner side of the is melted.

The particular form of resistance-band or 'retainn -heater screen illustrated-is espel* cially a vantageous when used' in this con.- nection, for the reason grainsof sugar and me ts them before they reach the strainer, the sections thereof permitting.l the ready passage of the sugar therebetween as fast as it is melted, and, moreover, enables allof the 3o sections of the vband tol be held in such close proximity to thestrainer tion is concentrated charge. x .Variouschanges for lthe abo'v'edescribed that the meltinfg close toV thel point o dis- ;5 construction .maybe made without departing .from thespirit and scope 'of my invention.
